As they say in AA (I'm not sure you're a fan, or not), despite our sobriety, we'll occasionally fall prey to being "powerless over people, places, & things." That's a product of being human in an imperfect world. I don't always walk around on a pink cloud of sobriety, but I certainly have more control over the things I say & do when I remain continually sober. It sounds like you're the same. I hope things improve with your neighbor. The situation you describe would certainly piss me off.
